I couldn´t reinstall my software

Hi, my name is Guillermo Mella, from Santiago, Chile. Please, could you help me retrieve my connection with Local by Flywheel. A week ago I downloaded this software and it run really good, but recently I had to reset o format my PC and since then I could not recover the use of this useful software. I could not connect anymore. I lost all my work and I am really troubled.

Thank you so much in advance
